From: Stefan Mätje <stefan.maetje@esd.eu> stable inclusion from linux-4.19.206 commit e5cc2285c6e7969d62e2bf1173ee8e1d4854a41b -------------------------------- commit 044012b52029204900af9e4230263418427f4ba4 upstream. This patch fixes the interchanged fetch of the CAN RX and TX error counters from the ESD_EV_CAN_ERROR_EXT message. The RX error counter is really in struct rx_msg::data[2] and the TX error counter is in struct rx_msg::data[3].
